If we accept any of the above grades (60 or 90 110 ksi), what are the precautions to be taken w.r.t. Recognized as socket weld fittings, Duplex Steel Socketweld Outlets are resistive to.What is theĪverage CE value for AISI 4130 forging material? All our 4130 Chromoly tubing has a smooth, seamless finish for use in.

We provide 4130 Chromoly tubes with wall thicknesses from 0.028 to 1.25 and O.D.s ranging from 3/16 to 12, standard lengths or cut to order.

Ěs per our standard, the maximum CE value is 0.43 but, suppliers proposed CE values ranges from 0.70 to 0.75. Factory Steel stocks Chromoly tube and thousands of other standard and specialty metal products to suit your project needs.

Is there any weldability issue with AISI 4130 90 ksi or 110 ksi material (high yield)? Unlike the standard products, RSP products have no other agencies approvals.

Ĝan we accept all above mentioned substitutional grades (yield strength: 60 ksi or 90 ksi or 100 ksi)?.

Our suppliers are claiming that all above mentioned grades are compatible and there will be no weldability issues with Conductor pipe material grade API 5L X-52. S3: Welding connector with material grade AISI 4130 100-110 KSI (forge) with CE value: 0.73-0.75 Steel casings shall be welded steel pipe of the diameters and plate thicknesses shown.

S2: Welding connector with material grade AISI 4130 90 KSI (forge) with Carbon equivalent (CE value): 0.71-0.73 Throughout this document wherever a referenced standard. Supplier 1: Welding connector w/material grade AISI 4130 60 KSI (forge) w/ Carbon equivalent (CE value): 0.7-0.73. This connector will be welded to Conductor Pipe (API 5L X-52, 30' Wall thickness WT 1') at Drilling Rig site.īut our suppliers are offering below material specs. We have some requirements for Welding connector (API 5L X-60 grade, 30' Wall thickness 1').
